Flex :: Instantiating View Won't Work?

We used to write our UnitTests with FlexUnit and we were just testing our model. Now we want to test the view too. Before i run my tests i create an instance of my view and my model to test the stuff. When i try to access the view i get a null pointer exception. If i add the view to the displaylist it somehow works - even if i remove it from the list right after adding.it looks something like this:

var myView: MyView = new myView();
//myView.initialize(); will throw error
Application.application.addChild(view);[code]..............
